Salatul faith-The Philosopher's stone

From the letters of the Jurist Sīdī Muhammad Aknusūs, may Allah be pleased with him

And know, O bother that no one approaches Allāh sincerely, with his inner being except that Allāh approaches him apart from all of existence. So he will not fail to obtain anything of the good of this world or the hereafter.
And I had been writing to you about what I think: that Ṣalāt al-Fātiḥī li mā ughliq in this time is more endowed than all other remembrances and more effective than all other secrets. And if only you were to remember it just as I have informed you, as part of your litanies 2000 in the day and the night, in addition to the (obligatory) litany. For that is the Greatest Treasure, and the Philosopher's Stone.
So, put all of your effort into being consistent with it and be ever vigilant at its blessed door, which is the door to the Presence of Allāh and His Messenger. For you will verily attain by it jewels , charismatic talents, secrets, lights, and gnosis, the worth of which cannot be measured. Whenever your concentration is set upon it, you will realize this, whatever be the circumstance. This is especially the case if you were to remember alongside it the Name that begins, "Yā Ghiyāthī ʼinda kulli kurbatin....." 99 times per day, or after every obligatory prayer- for the one who is able to. For anyone who sticks to that will discover all of the Secrets with ease, without any trouble, any hardship, any difficulty or condition.
And know that the People say that the Secrets have prescribed times and assigned limits. And it is not possible to receive anything from it before its time, nor after its time has expired.
I also had been informing you about Shaykh Abu Muḥammad Ṣāliḥ, that his Shaykh Abu Madyan al-Ghawth had directed him to Shaykh Mawlānā ʼAbd al-Qādir al-Jīlānī, may Allāh be pleased with them all.

Then, Abu Muḥammad Ṣāliḥ went to Baghdād. And Shaykh al-Jīlānī entered him into seclusion for three consecutive forty day periods, that is to say one hundred twenty days. But, there was no change in his spiritual state. So, he returned him to his shaykh Abu Madyan. And he stayed with him for a long time until the time came and he received his opening.
We only mention to him the traditions of the righteous to give lessons by their remembrance, to convince living hearts, and to sow in them the longing for the Bounty of Allāh.
Verily, this time in which we find ourselves does not support any great struggle whatsoever. And it is not possible to travel to any far off summit. And every door has been locked, as Shaykh Zarrūq and others have said. And there does not remain open any of them except the door of blessing upon the Messenger of Allāh, may Allāh bless him and grant him peace.

اللَّهُمَّ صَل عَلَى سَيِّدِنَا مُحَمَّدٍ ۞ الفَاتِحِ لِمَا أُغْلِقَ ۞ وَالخَاتِمِ لِمَا سَبَقَ ۞ نَاصِرِ الحَقِّ بِالحَقِّ ۞ وَالهَادِي إِلَى صِرَاطِكَ المُسْتَقِيمِ ۞ وَعَلَى آلِهِ حَقَّ قَدْرِهِ وَمِقْدَارِهِ العَظِيمِ ۩
